[css-writing-modes][css-pseudo][css-inline] text-combine-upright and initial-letter #653
Description
It is not clear what this should do
p {
writing-mode:vertical-rl;
text-orientation: sideways;
text-combine-upright: 2;
}
p::first-letter {
initial-letter: 3;
}<p>13 is a really nice number. Lorem Ipsum...</p>::first-letter should match the 1 at the beginning of the <p>, but that means it selects half of the text-combine-upright, and I have no idea of how you'd turn that into a 3-line drop cap.
I think there are three changes we could make to the specs to deal with that:
initial-letterhas no effect when applied to some-but-not-all the characters in a run of characters grouped by text-combine-upright::first-letterneeds to treat a run of characters grouped by text-combine-upright as single character and select all of it if it is the first thing in the element.::first-letterdoes not select anything if the element starts with run of characters grouped by text-combine-upright
Just for the record, I believe that text-combine-upright itself isn't an issue, and that the following ought to work just fine, highlighting that the issue is just due to selecting part of this orthogonal bit of content.
p {
writing-mode:vertical-rl;
text-orientation: sideways;
}
span {
text-combine-upright: all;
initial-letter: 3;
}<p><span>13</span> is a really nice number. Lorem Ipsum...</p>
